Germany’s Energie Baden-Württemberg AG (EnBW) has made its final investment decision on a large-scale battery storage project.
The publicly-traded energy company has announced the 400 MW / 800 MWh facility will be realized without government subsidies. It says the project will instead be financed through revenues from electricity sales and grid services.
Construction of the facility is scheduled to begin in early summer 2026, with the aim of being connected to the grid by the end of 2027.
The storage facility will be located on the site of the former Philippsburg nuclear power plant in southwestern Germany, where dismantling of the old reactors has been underway since 2017. EnBW formerly operated two nuclear power plants on site, which were taken offline in 2017 and 2020.
The project is one of several large-scale storage systems in Germany being built on sites formerly occupied by nuclear power plants.
Earlier this month, Vattenfall announced the construction of a 254 MW / 700 MWh battery storage facility at the former Brunsbüttel nuclear power plant. Meanwhile, RWE recently began building a 400 MW / 700 MWh battery storage facility at the former Gundremmingen nuclear power plant.
